- Sketch the graph of y=2cosx on the interval 2,92.arrow_forwardAs increases from 0 to 90, the value of csc tends toward _______.arrow_forwardConsider an angle with an initial ray pointing in the 3-o'clock direction that measures 0 radians. The terminal point on a circle centered at the angle's vertex is h radius lengths to the right of the circle's center and v radius lengths above the circle's center. The slope of the terminal ray of the angle is m. Match each of the following inputs/outputs with their corresponding variable. (You can use each variable once, more than once, or not at all.) -1 The input of the cos function а. V The output of the cos - 1 function b. h The input of the sin - 1 function С. т d. 0 | The output of the sin- function 1 v The input of the tan function v The output of the tan' - 1 functionarrow_forward
- A height of a rider on a Ferris wheel can be modeled using a sinusoidal function. The rider's height, h in meters, above ground vs time, t in seconds, can be described using the equation h = -16 cos(6t) + 18 11. a) Graph the rider's height above the ground during a 3-minute ride. b) Determine the height of the rider after 110 s. The Ferris Wheel 40 36 32 c) During the 3-minute ride, how long is the rider at or 28 above 26 m? 24 20 16 12 4. 30 60 90 120 150 180 Time (seconds)arrow_forwardPlease answer all subparts.
